Is "Step" a name only for Japanese girls? What does this name mean in Japanese?

It turned out that I thought it was, such as the famous star Ayumi Hamasaki, and Ayumi Nishizawa in "The Hayate the Combat Butler". But the Japanese light novel "Is This a Zombie?" "The male protagonist's name is Ayumi Aikawa. This confuses me a bit. Please help, is this a girl's name? Does anyone know what the meaning of this name is for Japanese parents to name their children?

**Many names of girls in big cities in Japan are now more gender-neutral. Unlike in the past, they were mostly "子", "美", etc., so "step" is the same for both men and women. It can be used. However, as 82645784 said above, many Japanese people use pseudonyms directly, so it is not very good to translate them into Chinese characters, and sometimes it may cause rudeness. But for some purposes, such as publicity and so on, in order for Chinese people to know and remember this person, both parties agree on an acceptable Chinese character to translate the name.

What does it mean when Japanese parents name their children? I'm afraid this outsider can't guess accurately. The reason is the same as above.
